Make sure /etc/umdns/ is accessiable for the umdns process if it
exists and umdns is run with umdns.@umdns[0].jail='1'.

The 'madvise', syscall is missing.
Found with 'utrace /usr/sbin/umdns' on an R7800 and RT3200.

Looks like 'openat', 'pipe2' and 'ppoll' are now needed, possibly due
to changes on libraries used by umdns now using slightly different
calls.
Found using
/etc/init.d/umdns trace
now use umdns, ie. cover all ubus call etc., then
/etc/init.d/umdns stop
find list of syscalls traced in /tmp/umdns.*.json

Now that ujail supports seccomp also on Aarch64, add missing syscall
'fstat' to the list of allowed syscalls.

This should fix an issue when user have a router with enabled seccomp
and tries to run umdns package which was build with SDK with disabled
seccomp support.

procd-seccomp switched to OCI-compliant seccomp parser instead of our
(legacy, OpenWrt-specific) format. Convert ruleset to new format.

The umdns init script includes function/network.sh globally, outside of any
service procedure. This causes init script activation to fail in buildroot
and IB context if umdns is set to builtin.
Additionally, the network.sh helper is not actually used.
Drop the entire include in order to repair init script activation in build
host context. Fixes FS#658.

This update includes numerous small fixes for:
1) Interfaces setup
2) Packets parsing
3) Sending replies
Without this there were multiple problems with exchanging information
between (u)mdns and other implementations (including (u)mdns as well).
This also follows project rename to umdns which was required to avoid
confusion with Apple's mdnsd from mDNSResponder project.
